1. Note the original setting of the brake lever adjuster in order that it can be returned to the same position when the bleeding operation is complete. Set the brake lever adjuster to position No.1.

1. Lever; 2. Adjuster wheel; 3. Triangular mark
2. Remove the cap from the bleed nipple on the right hand caliper.
3. Attach a transparent tube to the bleed nipple.

1. Bleed nipple; 2. Spanner; 3. Bleed tube; 4. Container
4. Place the other end of the tube in a suitable receptacle containing new brake fluid.
5. Turn the handlebars to bring the fluid reservoir to a level position.
6. Remove the screws from the reservoir cover.
Warning! Ensure absolute cleanliness when adding brake fluid to the brake fluid reservoir. Do not allow moisture or debris to enter the cylinder, as this will adversely affect the fluid properties. Always use fluid from a sealed container and do not use fluid from a container that has been opened for any period of time. Always check for fluid leakage around hydraulic fittings and for damage to hoses. A dangerous riding condition leading to loss of motorcycle control and an accident could result if this warning is ignored.
Caution! To prevent paint damage, do not spill brake fluid onto any area of the bodywork. Spilled brake fluid will damage paintwork.
7. Carefully remove the reservoir cover taking care not to spill any fluid.
8. Check the condition of the sealing diaphragm for the reservoir. Replace if necessary.

1. Diaphragm; 9. Release the bleed nipple
Warning! Use only DOT 4 specification brake fluid as listed in the general information section of this manual. The use of brake fluids other than those DOT 4 fluids listed in the general information section may reduce the efficiency of the braking system leading to an accident. Observe the brake fluid handling warnings given earlier in this section of the manual.
Note: During bleeding, do not allow the fluid level to fall below the lower level mark in the reservoir. If the fluid level is allowed to fall below this mark, air may enter the system and the sequence of bleeding must be repeated.
10. Slowly pull the brake lever to the handlebar and, holding the lever fully in, close the bleed nipple. Repeat steps 9 and 10 until no more air appears in the bleed tube, maintaining the brake fluid level between the upper and lower reservoir levels whilst bleeding is being carried out.
11. When all air has been expelled from the system, hold the lever in and close the bleed nipple. Tighten the nipple to 7 Nm.
12. Fill the reservoir to the upper level with new DOT 4 fluid.
Warning!
- Use only DOT 4 specification brake fluid as listed in the general information section of this manual. The use of brake fluids other than those DOT 4 fluids listed in the general information section may reduce the efficiency of the braking system leading to loss of motorcycle control and an accident.
- Observe the brake fluid handling warnings given earlier in this section of the manual.
Caution! To prevent paint damage, do not spill brake fluid onto any area of the bodywork. Spilled brake fluid will damage paintwork.
13. Remove the bleed tube.
14. Replace the bleed nipple cap.
15. Repeat the procedure for the left-hand caliper.
16. When both calipers have been bled, ensure the brake lever operation has a firm resistive feel to it, does not feel spongy and that the lever cannot be pulled directly back to the handlebar. Take remedial action as necessary.
17. Refit the diaphragm and reservoir cover. Tighten the screws to 2 Nm.
Warning! Always return the lever adjuster to the original setting as noted in paragraph 1. Operating the motorcycle with lever settings that are unfamiliar may lead to loss of control or an accident.
18. Reset the brake lever adjuster to the original setting.
19. Check the operation of the front brake. Rectify as necessary.
Warning! It is dangerous to operate the motorcycle with defective brakes and you must have your authorised Triumph Dealer take remedial action before you attempt to ride the motorcycle again. Failure to take remedial action may reduce braking efficiency leading to loss of motorcycle control and an accident.
